HEEL.

- Specification of Letters Patent. Patented Feb. 24, 1914:.

Application filed July 14, 19-13. Serial No. 778,878.

7 panying drawings.

This invention relates to cushion heelsfor shoes and to a dispositionthereof whereby a renewable tread surface is obtained that preventsslipping and prolongs the wear of the heel.

The-invention consists in the matters hereinafter set forth andparticularly pointed out in the appended claims.

In the drawings, Figure 1 is a plan View of a heel that embodiesfeatures of the invention; and Fig. 2 is avicw of the heel partia-lly'ininverted side elevation and partially broken away and in section.

Referring to the drawings, a heel body 1 of suitable contour andproportions is formed of rubber or like cushioning material with aseries of apertured and screwthreaded anchor plates 2 embedded therein.The face ofthe heel is recessed above each anchor plate and counterboredto receive a cylindrical plug 3 of rubber or like cushioning ,materialthat is secured as by a stud 4 engaging the companion anchor plate. Eachplug has an enlarged flanged head 5 with shoulders against the tread ofthe heel. Because of the flange which is preferably rounded, a cupped orrecessed tread face is given each plug which effectively prevents sideslipping. I 1

If the outen portions of the plugs toward the margins of the heel wear,they may be readily turned to bring a less worn portion into outerposition. As the rims or flanges compress and expand again at each stepof the wearer, any dirt that would otherwise be retained is ejected sothat the cupping effect. especially on a wet sprface is always present.As the plugs are readily replaced by new ones when fully worn, the bodyof the heel may be kept intact for an indefinite period. Thus the heelnot only has a long life but is effective in preventing slipping and inalways presenting a clean surface 'so that the cushioning effect is notlessened.

"Another advantage is the admission of air between the tread of the heeland the pavement, because of the heads of the inserts, so that theunpleasant effect of heat common with rubber heels of theusual'type, isobviated.

Obviously, changes in the details of construction may be made withoutdeparting from the spirit of my invention and I do not care to limitmyself'to any particular form or arrangement of parts. I

What I claim is 1. A cushion heel comprising a body of suitable materialhaving counterbored recesses in the tread face thereof, anchor platesembedded in the body, each adjacent arecess, plugs of cushioningmaterial rotatably inserted in the recesses and studs each securing aplug to its companion anchor plate, the outer faces of the plugs beingcupped.

2..A cushion heel comprising a body of suitable material havingcounterbored recesses in the tread face thereof, anchor plates embeddedin the body, each adjacent a recess, plugs of cushioning materialrotatably inserted in the recesses, and studs each securing a plug toits respective companion anchor plate, the outer-portions of the plugsbeing enlarged to shoulder against the heel tread and being providedwith marginal flanges that compress under weight and eject material fromthe resultant hollow faces of the plugs.

In testimony whereof I afiix my signature in presence of two witnesses.i WALTER H. VAUGHAN. Witnesses:
